Top Data Mining Techniques & Processes [2022]

As more and more businesses undergo a digital transformation, it is safe to say that data is now the building block of this new world. Companies everywhere are engaged in a fast-progressing race to master the finest data management system to optimize volume and speed. And that, in a nutshell, is what data scientists involved in top global organizations strive to achieve. 

The term data mining, also known as Knowledge Discovery in Data (KDD), refers to the process of deducing patterns and other important information from large sets of data. Many companies have increasingly adopted data mining techniques over the past decades to improve their decision-making capacity through insightful data analyses. Data mining techniques are used to sift through and organize data, identify user behaviors, uncover various permutations and combinations of information, and detect frauds, bottlenecks or security breaches.

But how exactly does data mining work? What are the different data mining techniques that data scientists deploy to better manage large volumes of data? Read on to find out. 

The Data Mining Process

There are primarily two processes that data mining techniques can be categorized into. The first is generating descriptions about the target dataset and the second is predicting outcomes and future trends. To arrive at satisfactory conclusions, data scientists go through several steps, from collection and visualization of data sets to extraction of information.

Many processes come to play before the data mining actually takes place. This pre-stage is called data mining implementation. It includes different methods such as business research to highlight the company’s objectives, quality checks for data, data cleaning, transforming raw data to final data sets, and data modeling to smoothen the analysis process. Data scientists use various techniques to observe patterns and correlations, which they then use to describe data. Similarly, classification and regression methods are used to classify data and identify anomalies. 

Data Mining Techniques

Data scientists heavily rely upon techniques and technologies derived from database management, machine learning and statistics to aid their work. Here are some data mining techniques that every data scientist must have at their fingertips.

1. Association

Association or the relation technique is perhaps one of the most used techniques in data mining. Here, an event and the correlation between its elements are observed to identify patterns. This technique finds a use case in retail where it is used for market basket analysis and determining buying behaviors of different customers.

2. Outlier Detection

Detection of anomalies or outliers in a data set is just as important as identifying patterns. An anomaly in a standard data set often provides key insight into favorable and replicable outcomes or drives a data scientist to better understand user behavior.

3. Identification Of Patterns

Identifying and tracking patterns in data sets is one of the most basic techniques in data mining. Recognizing a pattern usually involves detecting anomalies occurring at regular intervals or identifying the fluctuations in certain variables over time.

4. Classification In Data Mining

Classification in data mining is the technique of arranging various attributes of data together into predefined groups or categories, which are then used to draw more advanced conclusions. This is a slightly more complex process that finds its origin in machine learning and uses linear programming, decision trees, artificial neural networks and other techniques.

5. Clustering In Data Mining

Similar to classification, clustering in data mining is a technique used to create distinct and meaningful object clusters with similar characteristics. Unlike classification in data mining, where the groups are predefined, clustering uses data characteristics to define the groups.

6. Regression

Regression is a data mining technique that helps the data scientist to ascertain the probability of certain variables in correlation to others. It is used for planning, modeling, and to predict customer behavior. This convenient technique also uncovers the exact relationship between various variables in a data set.  

7. Prediction

As the name suggests, prediction allows the data scientist to project future data sets based on current and historical trends. Prediction often involves artificial intelligence and machine learning but is primarily conducted with the help of simple algorithms. 

With the help of data mining techniques, data scientists can chart and evaluate large sets of data and convert them into valuable information that strengthens the company’s functioning. Data mining has multiple applications in healthcare, education, retail, customer relationship management, finance and many other sectors. It is one of the most vital technologies in the digital industry that combines a variety of disciplines, especially machine learning, deep learning and artificial intelligence. Needless to say, data scientists who apply such data mining techniques regularly must have a solid understanding of these associated disciplines.

A Career In Machine Learning And Deep Learning Deep Learning and Machine Learning Careers

One important aspect to note is that businesses continue to struggle with scalability and automation despite the availability of advanced techniques and technology. That is why experienced, and skilled data scientists and engineers are in high demand by data-first companies. Data scientists are not only absorbed quickly by the largest digital companies in the world, but a career in this field comes with the assurance of a high package, long-term stability and growth potential.

With the rising popularity of big data and data warehousing, specializations in machine learning and deep learning have become key attributes that recruiters look for in potential candidates. Thus, if you are looking to scale up in your data science career, developing an aptitude in this niche is a good way forward. The largest recruiters in the world are on a continuous lookout for talented candidates with an education in data science and a specialization in machine learning. Additionally, internship or work experience adds weight to a candidate’s portfolio.
